I need help on the values on these questions?

Angle 6 is 135 degrees

Step-by-step explanation:

Reason why is because look at 45. (9x+14 is corresponding to that so they must have the same values.

meaninng 180-45 gets you 135. So, 135 is the measure of angle 6

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

answer: its the third option.

step-by-step explanation:

i just took the test.
